JOHN HYSLOP, JR, OF ABING'ION, MASSACHUSETTS.

TAPERED NAIL.

SPECIFICATION forming part of Letters Patent No. 373,234, dated November15, 1887.

Application filed July 1, 1887. Serial No. 243,090. (No model.)

To all whom it may concern:

Be it known that 1, JOHN HYSLOP, Jr., of Abington, in the county ofPlymouth and State of Massachusetts, have invented a new and ImprovedNail, ofwhich the following is a full, clear, and exact description.

My invention relates to an improved nail which may be driven easily andtruly and without splitting the work, and will hold well when drivenhome.

The invention .consistsin a nail made by first cutting a blank intapering form edgewise from a metal plate, and subsequently subjectingthe blankv to sidewise pressure to finish the nail by bringing thelonger dimensions of I the point of the nail about parallel with thelonger dimensions of the upper part or head portion of the nail.

Reference is to be had to the accompanying drawings, forming a part ofthis specification, in which similar letters of reference indicatecorresponding parts in all the views.

Figure l is a perspective view of a cut nailblank. Fig. 2 shows a nailas finished by sidewise pressure on the blank; and Fig. 3 shows opposingdies andthe nail-blank about being fed between them, and also thefinished nail as it appears in edge View after being operated upon bythe dies.

My improved nail is made by first cutting a nail-blank in wedge ortapering form from a plate of, metal in the ordinary or any approvedway, and then subjecting the opposite sides ofthe blank to pressure bydies to taper the sides of the nail to give the finished nail a pointthe longer dimensions of which range about parallel with the longerdimensions of the upper part or head portion of the nail. The finishednail will preferably be tapered from all sides and for its whole length.In the example shown in the drawings the nailblank A (shown in Fig. 1)has a point,a, which, in direction of its length, ranges transversely tothe longer dimension of the head a of the blank, and the finished nail B(shown in Fig. 2 of the drawings) is produced by subjecting the oppositesides of the blank A to pressure between dies to an extent which willtaper the sides of the nail and press the nail-point b, so

that for its longer dimension it rangesabout naila shoe-nail, forinstancefinished in the form of the blank A its right-augularly-disposedpoint and head portions both try to guide or influence the position ofthe nail,

and there is a conflict,so to speak,which tends to twist the nail in thework and prevents driving the nails home square with each other; hencethe heads of such nails when driven range in all directions. Byfinishing the nail as shown at B, with its point ranging about parallelwith its head portion, this difficulty or conflictis obviated, and thenail drives straight and will not twist in the work, and may be drivenmore easily, and will hold better, and will not split the work, andthese nails driven in a row will present a uniform appearance at theface of the finished work, all of which are desirable qualities.

Having thus fully described my invention, what I claim as new, anddesire to secure by Letters Patent, is

1. As a new article of manufacture, a nail having the longer dimensionof its point about parallel with the longer dimension of the upper partor head portion of the nail, substantially as herein set forth.

2. As a new article of manufacture, a nail tapering on all sides, andhaving the longer dimension of its point about parallel with the longerdimension of the upper part or head portion of the nail, substantiallyas herein set forth. I
